In order to find a fast working and low-dimensional equivalent with dynamic Neural Networks (NN), several model reduction approaches has been tried, including aggregation, PCA transformation, and bottleneck NN compression. Reduced data were used to train dynamic NN. Simulations with the NN model produced trajectories which agreed well with the original trajectories of TOMGRO.

Control actuators are provided by two pairs of reactive jets with constant directions of their torques. Characteristics of these jets could be unequal. The time of the process of a transfer from the initial to the end point in the body-fixed frame of angular velocities is not prescribed. Both initial and end points could be arbitrary but given in advance. The problem is solved in the closed analytical form. Sufficient conditions of optimality are used.
